This question is in my test, it seems pretty simple but I can't able to solve it 
2007 A/R = $376,000
2007 Sales= $3,570,000
A marketing firm present offers term of 2/10 net 30 to its commercial customers (85% percent of firms dollar sales). Assuming that firm changes its terms to 2/10 net 45 and all its commercial customers take advantage of the change and pay 15 days later than before, the approx. effect on the company's credit needs in 2007 would be:
1- decrease of $250,000
2- increase of $215,000
3- increase of $147,000
4- increase of $188,000
Thanks in advance
